Substantive analytical procedures.
SUBSTANTIVE ANALYTICAL PROCEDURES Analytical Procedures is one of financial audit skill which help an auditor understand the client's business and changes in the business, to identify potential risk areas and to plan other audit procedures.
A thorough understanding of analytical procedures is becoming more and more important to the effective and efficient performance of an audit. In this article, Ray Whittington Whit·ting·ton , Richard 1358?-1423.

Statement on Auditing Standards no. 56, Analytical Procedures, effective for audits of financial statements for periods beginning on or after January 1, 1989, makes analytical procedures a required part of the planning and overall review phases of an audit. It also says analytical procedures may be the most effective or efficient substantive procedures for obtaining evidence about certain financial statement assertions.

Founded in 1976, SAS is one of the world's largest privately held software companies. See SAS System. no. 56 says an auditor auditor n. an accountant who conducts an audit to verify the accuracy of the financial records and accounting practices of a business or government. A proper audit will point out deficiencies in accounting and other financial operations. can rely on substantive procedures to achieve an audit objective through tests of details, analytical procedures or a combination of both. The auditor's decision about the procedures to use depends on what is expected to be more effective and efficient. This is a two-step process. The auditor
1. Determines the overall level of assurance required from the substantive procedures, based on assessments of inherent and control risks.
2. Determines the appropriate mix of substantive tests (analytical procedures and tests of details) based on the nature of the assertion and the tradeoffs between the levels of assurance the tests provide and the time involved in performing them.
Substantive procedures. When performing substantive analytical procedures, the auditor develops an expectation about a current financial statement amount using other data--such as comparable prior years' amounts, industry statistics or budgeted amounts. The auditor then compares the expectation to the current amount and investigates any significant differences that resulted.
The most important consideration in determining the extent of the assurance obtained from an analytical analytical, analytic

In evaluating the precision of the estimate, SAS no. 56 says the auditor should consider the completeness of the data used to develop the expectation and the level of detail. Broad-level (for example, year-to-year numbers) expectations aren't generally as precise as expectations developed using more detailed (for example, monthly) data. Other factors affect precision, such as the reasonableness and predictability of the relationship between the current amount and the data used to make the prediction and the reliability or accuracy of the data. Therefore, the extent of the analytical procedures that can be performed largely depends on the data that are available to develop the expectations--a factor largely outside the control of the auditor.
Tests of details. Since analytical procedures often are the most efficient form of substantive tests, the auditor typically determines the extent of assurance that may be obtained from them about an assertion and then determines how much, if any, assurance must be obtained from tests of details. When tests of details are necessary, audit sampling may be involved. In these circumstances CIRCUMSTANCES, evidence. The particulars which accompany a fact.
2. The facts proved are either possible or impossible, ordinary and probable, or extraordinary and improbable, recent or ancient; they may have happened near us, or afar off; they are public or , exhibit 1 at right illustrates the tradeoff between reliance on analytical procedures and the extent of tests of details. It uses the formula for nonstatistical samples for tests of details in exhibit 2 at right from the American Institute of CPAs audit and accounting guide Audit Sampling. Exhibit 1 indicates the sample size goes from 60 to 46 to 30 as the extent of assurance from analytical procedures goes from none to moderate to substantial.
A combination. Analytical procedures also may be combined with tests of details when sampling isn't used. Many financial statement accounts--especially those made up of relatively few items--may be more efficiently audited by focusing on the high dollar (key) items instead of applying audit sampling. In these cases, tests of details may be applied to the key items with analytical procedures used to provide evidence about the remaining balance of the account.
INVESTIGATING SIGNIFICANT DIFFERENCES
When using analytical procedures as a substantive test, the auditor must decide what amount of difference between the current financial statement amount and the expectation can be accepted without investigation. This decision will depend on the auditor's judgment about materiality MATERIALITY. That which is important; that which is not merely of form but of substance.
2. When a bill for discovery has been filed, for example, the defendant must answer every material fact which is charged in the bill, and the test in these cases seems to of the difference, but the degree of assurance desired from the procedure also is important. The more assurance that's desired from the procedure, the smaller the acceptable difference.
When substantive analytical procedures are used, the auditor is relying on them and reducing other substantive procedures. Therefore, any significant fluctuations must be investigated thoroughly. If management has an explanation for the difference, the auditor should corroborate To support or enhance the believability of a fact or assertion by the presentation of additional information that confirms the truthfulness of the item.
The testimony of a witness is corroborated if subsequent evidence, such as a coroner's report or the testimony of other it with other evidence. If management can't explain the difference, the auditor should perform sufficient procedures to determine that the difference is not the result of a material misstatement mis·state
